Problems solved by technology

In the actual product assembly, due to the differences of each product, such as the length difference of the three-phase leads of the motor, the oxidation of the contacts, etc., the parameters of the stator resistance and inductance of the motor usually change, resulting in the current value of these parameters and the actual value. The situation does not match. Among them, the change of stator inductance can easily lead to inaccurate motor control models, and then problems such as difficulty in starting the motor with load

Abstract

The invention discloses a motor parameter adaptive adjusting method, a device, a motion control system and an unmanned plane; the method comprises the following steps: executing a set motor start control according to a motor start order; obtaining the present rotating speed of the motor under the start control; obtaining the present time duration of the executed motor start control; when the present time duration reaches a set time threshold yet the present rotating speed cannot reach a set rotating speed, diagnosing the motor to have a start failure; measuring the motor stator inductance so as to obtain the stator inductance true value according to the diagnosis result of the start failure; correcting the stator inductance present value as the obtained true value.

Description

technical field [0001] The present invention relates to the field of motor control, and more specifically, the present invention relates to a motor parameter adaptive adjustment method, a motor parameter adaptive adjustment device, a motion control system, and an unmanned aerial vehicle. Background technique [0002] At present, for electromechanical products powered by batteries, such as unmanned aerial vehicles, the endurance time has always been a difficult problem to solve. As the main power consumption part of such electromechanical products, the motor drive seriously restricts the endurance time, so improving the working efficiency of the motor drive is of great importance. very important practical significance. [0003] With the further development of motor control technology, the emergence of new control algorithms has made an important contribution to improving the efficiency of motor drives. For example, the field-oriented control (FOC) control algorithm has been u...
